Controversy exists over how many embryos should be implanted during assisted conception (in-vitro fertilisation/IVF) therapy. New research by the University of Bristol and published in the The Lancet shows that, while discretion can be applied in whether to implant one or two embryos, three or more should never be implanted into women of any age. The findings have been covered by national and international media.
